Claims. (Cl. 230-434) This invention relates toair cooling apparatus,

louvered fan or in combination with air conditioning equipment installed in Windows or air ducts and embodying a system of louvers which may be adjusted to control the directional flow of air into and out of the unit as desired.

Another object of the invention resides in the provision of an air cooling device which is compactly housed within an attractive cabinet having ample openings, both front and rear, for the intake and discharge of air therethrough and havmg suitable adjustable closures arranged both vertically and horizontally whereby air currents passing through the device, and impelled by the fan unit therein, can be completely regulated as to volume and directional movement to provide the maximum benefit of the circulated air.

An obj ect of the invention is that of providing an air cooling unit which may be economically constructed and provide adequate air control without the use of thermal switches, regulated by temperatures, or other expensive devices, ordinarily provided for controlling the air volume and temperature toinsure the desired result.

Broadly, the invention contemplates the provision of an economical, light and attractive, air cooling unit in which an electric fan of any conventional type may, be installedand the entire unit moved about thepremises and utilized in any desired position or location with a minimum of effort, and adevice whichafiords adequate con-,

trol of the volume and directional flow of the air by the simple adjustment of thenovel arrangement of louvers.

While the foregoing objects are paramount,

other and lesser objects will become manifest as the description proceeds, taken in connection with the appended drawings wherein:

Figure 1 is a vertical transverse sectional view of the invention, takenon lines ll of Figure 2,

illustrating the arrangement of horizontally 2 rangement of the adjustable louvers and illustrating the fan. i

Figure 4, is a fragmentary lateral cross-sectional View ofthe cabinet illustrating a modified form thereof and showing a series of stationary louvers in oneend while the back of the cabinet i shown closed;

Figure 5 is a fragmentary perspective View of one of the vertical louvers. t

Figure 6 is a front elevational"-view fragmentarily showing the tensioned pivotal mounting of the vertical louvers.

Figure 7 schematically illustrates the layout of the housing which may be stamped in a single sheet of metal and formed as a unit, and

Figure 8 is a perspective illustration of a modified form of one of the vertical louvers having embossments therein for rigidity.

The invention primarily comprises a' cabinet II] which is preferably open on both sides, or the front and rear, and it is preferable to economically form the cabinet H] from a single strip of metal by stamping the same in substantially the shape illustrated in Figure'l. By this procedure the cabinet :0 may be assembled quickl vand economically while providing a substantialstructure. The top and bottom portions l l and 12 may be oval, circular,orhex agonal in form, as desired, and connected by the narrower end portions It and I4, the strips being broken at right angles on the dotted line a to form the cabinet llll;

members by the iyerticalarrangementof spaced louvers 15 whichare pivotally mounted between i the top and bottom members Hand is, in the manner illustrated in Figures 1 and 2, andsuch trating the adjustability oi the vertically arranged louvers in the front andrearof the cabinet. l.

Figure 3 is a front elevation al viewl oflthe invention, showing the verticaland-horizontal-arlouvers may extend entirely around the assembly, acrosstheends as well as thefront and rear sides of thecabinet H3. The top and bottom members II and I2, aswell as the sidemembers ltiand Hi, may be properly embossed to insure adequate rigidityfor the structure. H

'lhe adjustable louvers are illustrated in detail in Figures ,5 and 6 and maybe formedoi a double, thickness of sheet materials and streamlined so that their outer edges are} relatively thin. Each vertical louveris rigidly, supported onfa shaft I6 which is pivoted at each endf'in the topand bottom members II and 12 oi the cabinet Illso that the louvers 15 can bemoved individually to any "position desired, as. shown inEigures 2 and 4,, to control the directional flow oifair through the cabine t [,Of this arclosed or partially closed, as shown in Figure 2, in accordance with room temperatures or the required volume of air sought to be blown out by the fan ii in the cabinet iii. The amount of air circulated by the fan I? depends upon the volume drawn in from the rear of the cabinet and if it is desirable to increase or decrease this volume the louvers l5 at the rear of the cabinet Ill can be adjusted accordingly.

It is desirable to mount the louvers l5 so that they may have a tensioning device at one or both ends by which the members l5 can be adjusted and retained in their adjusted position. In Figure 6 is fragmentarily illustrated one of the louvers 15, its supporting shaft [6, and a fragmentary portion of the top ll through which the shaft [6 is pivoted. A spring i8 is arranged between the top I i and about the shaft l6 and bears downwardly against a washer i9 arranged on the top of the louver 15 to frictionally hold the louver H3 in its adjusted position. I

A modified form of the arrangement for mounting the louvers i5 is shown in Figure 3,

all of the louvers i5 being mounted in a unitary structure, the upper and lower ends of the shafts i6 thereof, being pivotally arranged in mounting brackets 20 and 28 which consist of long 'narrow strips conforming to the contour of the top and bottom members I I and 12 of the cabinet Hi and secured at each end by screws 22. The ends b of the members 20 are bent so as to offset the main body portions of the brackets I 28 to space these portions from the top and bottom members Ii and I2 of the cabinet It and accommodate the tensioning devices l8 arranged along the top of the louver assembly, in the manner illustrated in Figure 3.

A plurality of spaced horizontally arranged louvers are arranged in the front of the cabinet I0, as shown in Figures 1 and 3, and preferably have their pivoting mounting shaft 24 arranged through their axes, as shown in Figure 1, so that these'members can be partially rotated on their pivots for up or down adjustments. Obviously, the louvers 23 may be independently or collectively actuated as desired, it being necessary only to connect all of the louvers 23 by a common lever (not shown) which may be actuated to move the louvers 23 as a unit. However, it is desirable that these be independently operative in order to properly. and effectively direct air currents up or down, as desired.

' The louvers 23 may be mounted on brackets 25 vertically arranged on each end of the cabinet [0, as shown in Figure 3, and installed or removed as a unit in the same manner as the vertical arrangement of louvers B5 are arranged in the structure shown in Figure 3. Springs 26 may be provided on one or both ends of the shaft 2 1 of the louvers 23 .to provide tensioning devices similar to the members it of the vertical arrangement of louvers l5. In Figure 8 is illustrated another form of louver which is formed from a single thickness of material and bent at each end at to provide a pivotal mounting on the shafts l6 or2 i and may be employed in either the horizontal or vertical arrangement of louvers. The louver i523, shown in Figure 8, is preferably provided with longitudinal embossment d to afford the desired rigidity.

Obviously, the cabinet It may be closed at its rear, as shown in Figure 4, if desired, and stationary louvers 2! formed in its end members I3 and 14. It is necessary, however, that some opening be provided in the rear of the cabinet Iii and behind the fan II to insure the proper function or the latter. The fan It may be of a conventional type, capable of being removed if desired and utilized outside of the cabinet It. In Figure 1 the fan I! is illustrated in the cabinet 20 and secured by a strap 28 arranged across its base 2:; and held by a thumbnut 30 on a bolt 3| extending through the bottom l2 of the cabinet W. A suitable handle 32 is arranged in the top H of the cabinet ill for convenience in handling the apparatus.

Manirestly, the structure herein shown and described is capable of considerable modification from time to time by persons skilled in the art without departing from the spirit and intent of the invention or the scope of the appended claims.
